During President Barack Obama's speech in Elkhart, Indiana, on Wednesday, he didn't mention presumptive Republican nominee Donald Trump by name — but as the New York Times reported, there was no mistaking who Obama was railing against during his time behind the mic.

While much of the focus was on the president's strident foray into the 2016 election, one moment during his speech has been getting attention: Obama's very noticeable stutters and extra long pauses while making a point about "divisions."

“If we turn against each other based on divisions of race or religion," he began — and then the president seemed to have trouble coming up with the words to follow "if," which he repeated multiple times.

Obama then came back with a warning to not fall "for a bunch of okie doke just because, you know, it sounds funny or the tweets are provocative” — along with some noticeable pauses — "then we won’t build on the progress that we’ve started.”

Here's the clip:

And as you might expect, Twitter was none too kind:
